Bopped

Derek Haven had always had a bit of an obsessive streak in him. That was something that was as true as the sky being blue. His mother, being his mother did not call it obsessive though. She called it being 'determined'. His uncle, who did not see the need to hold back his true thoughts on a matter, had never once held back on what he thought about that particular trait of Derek's. 

He had called Derek, bull-headed, he had called him a leech. Sticking to a point and then sucking on it slowly until there was nothing left. And then he had also called him a stubborn mule that did not know when to give up.

While both observations described the same thing in vastly different ways. Derek did not disagree with either of them, they were both right afterall. He was stubborn, and once his mind was fixed on something. He never gave up until he obtained it.

That was just the way that he was.
